T0 ZZ 107mm it may concern.' i

Be it known that I, JOHN C. TURNER, a citizen of the United States, residing at Dayton, in the county vof Montgomery and State of Ohio, have invented certain new and useful Improvements in a Flywheel and Iinion Construction for Toys, of which the following is a specification.

This invention relates to new and useful improvements in a fly wheel and pinion construction, and has particular reference to a fly wheel and pinion of the laminated type for use in toys.

Une of the principal objects of my invention is to provide for toys, a laminated fly wheel and pinion construction which may be economically manufactured, and which is easily assembled and positively mounted on the spindle. The lainiiiations forming the pinion are stamped out of a suitable strip of metal, and are so mounted on the spindle that the lubricant may easily work between them. On the same spindle the fly wheel. discs are also mounted, face to face, to provide a fly wheel which has atrue balance and a positive mounting on it.

Other importa-nt and incidental objects will be brought out in the following specification, and particularly set forth in the subjoined claims.

In the accompanying drawings, Figure l is a side elevational view of my toy motor, with the wheel on the near side removed to show my laminated pinion construction. Figure 2 is a plan view of the motor, showing the laminated pinion and fly wheel mounted on the spindle. Figure 3 is a sectional view taken through the fly wheel on the line 3 3 of 'Figure 2. Figure 4l is a sectional view on the line 4-4 of Figure 2,

showing one of the pinion discs mounted on a [lat milled portion of the spindle. And Figure 5 is a sectional view takenl on rthe line 5--5 of Figure 2, showing how the met.- al ou the sides of the spindle is upset by staking to hold the fly wheel and pinion in position on it.

Referring to the accompanying drawings for a detailed description of my invention,

the numeral 1 designates a sub-frame in which is Journaled an axle'shaft 2 on which are fast ground wheels 3, 3. Fast on the axle shaft 2 within the sub-frame l, isy a gear 4c that is adapted to be driven'by im- 1924. semi No.' 710,947.

provedpinion and vfly' wheel construction now to be described.y r 1 I.

.Iournaled within the sub-frame 1 a short distance'from the axlefshaft 2,'is a spindle 5. On its end opposite the gear 4 ,two sides 6, 6 of the spindle'are milled. flat for a certain `portion of its length to receive a series ofthin toothed-stampings7, each Vone of which has a squared central hole that is adapted to lit the llat part of the spindle for a positive mounting thereon. These stampings are economically made, and when they aremounted on the spindle they form a pinion which engages the gear 4: t-o rotate the i latter when the spindle is turned. (See Figures 2 and t.)

After the pinion stampings 7 are fitted-on the flat portion of the spindle 5, burs or upv set portions 8 are formed `on it to engage the outside one of the stampings to hold them on the spindle. The inward movementv of the stampings is limited bythe shoulders which are formed at thefinner ends of the flat surfaces on the spindle.` Between this shoulder and the burs 8, the stampings 6y are so mounted on the spindle asl to `form a sturdy and positively drive-n pinion between whose laminationsgraphite or any other lubricant may freely work at all times.

' A short distance from its pinion receiving part, the spindle 5 has two flatmilled sides 9, 9 to form for a short portion of its length a flattened part adapted to receive a series of punchings 10 that have squared central holes adapted to fit this flattened part of the spindle for a positive mounting thereon. These punchings l() are of disc form, as shown in Figures Vl, 2 and 3, and when mounted face to face on the flattened part of the spindle defined by its sides 9, 9, they foi-1n together a balanced fly wheel in which energy is stored for propelling the toy spaces 9 on the spindle, solidly hold the discs 10 between them to provide a fly wheel which is economically made for efficient service. l

It will thus be seen that I have provided for toys, or for any other desired use, a fly Wheel and pinion construction that may be cheaply made, easily assembled and eiiiciently operated. y n v a Having described my invention, I claim: l. In a device of the'type described, the

combination With a spindle, of a series ofk toothed-dise stampings having `squared leentral holes, said spindle being formed With a flattened portiony upon which said stampings are fitted, face to face, to form a pinion, a gear in engagement with said pinion, and

means formed on thev spindle to `hold said fitted, face to face, on vsaid iiattened portion ot the spindle to form ay pinion, a gear in engagement with the latter, and burs formedon the spindleto engage the outer one of s'aid'stampings after the flatter are mounted on the flattenedV portion of said spindle.

3. A device 'of the type described comprising'a spindle flattened at one end, a series of v toothed stampingswith squared holes, titte-d on said flattened end of the spindle to form a pinion, and upsets formed on said fiat` tened end beyond the stampings to hold *L them against the shoulder at the inner end of its flattened portion.

In testimony whereof- I have hereunto set my hand this 25thv-r day of April,'1924.
